#3 She was overlooked in front of Charlotte and Sasha Banks

Becky Lynch had a huge triple threat match against Charlotte and Sasha Banks at WrestleMania 32 which saw the Divas Championship being retired and replaced by the Women's Championship.
It was Charlotte who won the match after making Becky tap-out to her Figure 8 submission lock. While she was never the favorite in that match, there was a particular incident that really made her feel neglected, overlooked, and embarrassed.
During a press event before WrestleMania 33, Mattel surprised Charlotte and Sasha Banks with some dolls to celebrate their historic match last year, but completely forgot the third participant in that match, Becky Lynch.
While not getting a doll is not a huge thing, but being ignored like that made her realize she was not the favorite of the media, who treated Charlotte and Sasha Banks as bigger stars than her. In the episode, she was extremely frustrated while sharing this moment with us.
